  • modifying ajax returned data before showing

    - by Nick
    I'm processing subscribtion form with jQuery/ajax and need to display results with success function (they are different depending on if email exists in database). But the trick is I do not need h2 and first "p" tag. How can I show only div#alertmsg and second "p" tag? I've tried revoming unnecessary elements with method described here, but it didn't work. Thanks in advance. Here is my code: var dataString = $('#subscribe').serialize(); $.ajax({ type: "POST", url: "/templates/willrock/pommo/user/process.php", data: dataString, success: function(data){ var result = $(data); $('#success').append(result); } Here is the data returned: <h2>Subscription Review</h2> <p><a href="url" onClick="history.back(); return false;"><img src="/templates/willrock/pommo/themes/shared/images/icons/back.png" alt="back icon" class="navimage" /> Back to Subscription Form</a></p> <div id="alertmsg" class="error"> <ul> <li>Email address already exists. Duplicates are not allowed.</li> </ul> </div> <p><a href="login.php">Update your records</a></p>

  • Persistence provider for Java that supports final fields

    - by naeron84
    I'm very new to Java but I've been developing a habit to use final wherever possible declaring immutability which i think is a good thing. (Consider f#) I've read that JPA does not support final fields. Hibernate, TopLink? I'm not sure about these but i prefer JPA for now. Is that even possible theoretically - let's say through reflection - to modify final fields after creation? My guess would be... NO :) What would be certainly possible for a persistence solution is to support constructors with parameters. At least i see no reason that would make this impossible. Mapping would be a little tricky i guess. This is an alternative solution. Suggestions?

  • Problem with GWT behind a reverse proxy - either nginx or apache

    - by Don Branson
    I'm having this problem with GWT when it's behind a reverse proxy. The backend app is deployed within a context - let's call it /context. The GWT app works fine when I hit it directly: http://host:8080/context/ I can configure a reverse proxy in front it it. Here's my nginx example: upstream backend { server 127.0.0.1:8080; } ... location / { proxy_pass http://backend/context/; } But, when I run through the reverse proxy, GWT gets confused, saying: 2009-10-04 14:05:41.140:/:WARN: Login: ERROR: The serialization policy file '/C7F5ECA5E3C10B453290DE47D3BE0F0E.gwt.rpc' was not found; did you forget to include it in this deployment? 2009-10-04 14:05:41.140:/:WARN: Login: WARNING: Failed to get the SerializationPolicy 'C7F5ECA5E3C10B453290DE47D3BE0F0E' for module 'https://hostname:444/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result. 2009-10-04 14:05:41.292:/:WARN: StoryService: ERROR: The serialization policy file '/0445C2D48AEF2FB8CB70C4D4A7849D88.gwt.rpc' was not found; did you forget to include it in this deployment? 2009-10-04 14:05:41.292:/:WARN: StoryService: WARNING: Failed to get the SerializationPolicy '0445C2D48AEF2FB8CB70C4D4A7849D88' for module 'https://hostname:444/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result. In other words, GWT isn't getting the word that it needs to prepend /context/ hen look for C7F5ECA5E3C10B453290DE47D3BE0F0E.gwt.rpc, but only when the request comes throught proxy. A workaround is to add the context to the url for the web site: location /context/ { proxy_pass http://backend/context/; } but that means the context is now part of the url that the user sees, and that's ugly. Anybody know how to make GWT happy in this case? Software versions: GWT - 1.7.0 (same problem with 1.7.1) Jetty - 6.1.21 (but the same problem existed under tomcat) nginx - 0.7.62 (same problem under apache 2.x) I've looked at the traffic between the proxy and the backend using DonsProxy, but there's nothing noteworthy there.

  • Problem using FluentNHibernate, SQLite and Enums

    - by weenet
    I have a Sharp Architecture based app using Fluent NHibernate with Automapping. I have the following Enum: public enum Topics { AdditionSubtraction = 1, MultiplicationDivision = 2, DecimalsFractions = 3 } and the following Class: public class Strategy : BaseEntity { public virtual string Name { get; set; } public virtual Topics Topic { get; set; } public virtual IList Items { get; set; } } If I create an instance of the class thusly: Strategy s = new Strategy { Name = "Test", Topic = Topics.AdditionSubtraction }; it Saves correctly (thanks to this mapping convention: public class EnumConvention : IPropertyConvention, IPropertyConventionAcceptance { public void Apply(FluentNHibernate.Conventions.Instances.IPropertyInstance instance) { instance.CustomType(instance.Property.PropertyType); } public void Accept(FluentNHibernate.Conventions.AcceptanceCriteria.IAcceptanceCriteria criteria) { criteria.Expect(x = x.Property.PropertyType.IsEnum); } } However, upon retrieval, I get an error regarding an attempt to convert Int64 to Topics. This works fine in SQL Server. Any ideas for a workaround? Thanks.

  • Java resource closing

    - by Bob
    Hi, I'm writing an app that connect to a website and read one line from it. I do it like this: try{ URLConnection connection = new URL("www.example.com").openConnection(); BufferedReader rd = new BufferedReader(new InputStreamReader(connection.getInputStream())); String response = rd.readLine(); rd.close(); }catch (Exception e) { //exception handling } Is it good? I mean, I close the BufferedReader in the last line, but I do not close the InputStreamReader. Should I create a standalone InputStreamReader from the connection.getInputStream, and a BufferedReader from the standalone InputStreamReader, than close all the two readers? I think it will be better to place the closing methods in the finally block like this: InputStreamReader isr = null; BufferedReader br = null; try{ URLConnection connection = new URL("www.example.com").openConnection(); isr = new InputStreamReader(connection.getInputStream()); br = new BufferedReader(isr); String response = br.readLine(); }catch (Exception e) { //exception handling }finally{ br.close(); isr.close(); } But it is ugly, because the closing methods can throw exception, so I have to handle or throw it. Which solution is better? Or what would be the best solution?

  • Google App Engine - Uploading blobs and authentication

    - by Keyur
    (I tried asking this on the GAE forums but didn't get an answer so am trying it here.) Currently to upload blobs, the app engine's blob store service creates a unique one- time URL that a user can post blobs to. My requirement is that I only want authenticated / authorized users to post blobs in my application. I can achieve this currently if the page that includes the multipart form to upload blobs is in my application. However, I am looking to providing a "REST API" for my users to upload their blobs. While it is true that the one-time nature of the upload URL mitigates the chances of rogue use but it's still possible. I was wondering if there is anyone on the app engine team here that can consider a feature where developers can register an upload listener. (Or if there is already a way, I'll be all ears). A standard servlet filter could also potentially do the job. This will give us an opportunity to authenticate / validate / decorate requests before the request gets forwarded to the blob store service. Thanks, Keyur

  • ASP.Net HttpModule List<> content

    - by test
    We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

  • In what order does DOJO handles ajax requests?

    - by mm2887
    Hi, Using a form in a dialog box I am using Dojo in jsp to save the form in my database. After that request is completed using dojo.xhrPost() I am sending in another request to update a dropdown box that should include the added form object that was just saved, but for some reason the request to update the dropdown is executed before saving the form in the database even though the form save is called first. Using Firebug I can see that the getLocations() request is completed before the sendForm() request. This is the code: Add Team sendForm("ajaxResult1", "addTeamForm"); dijit.byId("addTeamDialog").hide(); getLocations("locationsTeam"); </script> function sendForm(target, form){ var targetNode = dojo.byId(target); var xhrArgs = { form: form, url: "ajax", handleAs: "text", load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrPost(xhrArgs); } function getLocations(id) { var targetNode = dojo.byId(id); var xhrArgs = { url: "ajax", handleAs: "text", content: { location: "yes" }, load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrGet(xhrArgs); } Why is this happening? Is there way to make the first request complete first before the second executes? To reduce the possibilities of why this is happening I tried setting the cache property in xhrGet to false but the result is still the same. Please help!

  • WCF and ASP.NET - Server.Execute throwing object reference not set to an instance of an object

    - by user208662
    Hello, I have an ASP.NET page that calls to a WCF service. This WCF service uses a BackgroundWorker to asynchronously create an ASP.NET page on my server. Oddly, when I execute the WCF Service [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] public void PostRequest(string comments) { // Do stuff // If everything went o.k. asynchronously render a page on the server. I do not want to // block the caller while this is occurring. BackgroundWorker myWorker = new BackgroundWorker(); myWorker.DoWork += new DoWorkEventHandler(myWorker_DoWork); myWorker.RunWorkerAsync(HttpContext.Current); } private void myWorker_DoWork(object sender, DoWorkEventArgs e) { // Set the current context so we can render the page via Server.Execute HttpContext context = (HttpContext)(e.Argument); HttpContext.Current = context; // Retrieve the url to the page string applicationPath = context.Request.ApplicationPath; string sourceUrl = applicationPath + "/log.aspx"; string targetDirectory = currentContext.Server.MapPath("/logs/"); // Execute the other page and load its contents using (StringWriter stringWriter = new StringWriter()) { // Write the contents out to the target url // NOTE: THIS IS WHERE MY ERROR OCCURS currentContext.Server.Execute(sourceUrl, stringWriter); // Prepare to write out the result of the log targetPath = targetDirectory + "/" + DateTime.Now.ToShortDateString() + ".aspx"; using (StreamWriter streamWriter = new StreamWriter(targetPath, false)) { // Write out the content to the file sb.Append(stringWriter.ToString()); streamWriter.Write(sb.ToString()); } } } Oddly, when the currentContext.Server.Execute method is executed, it throws an "object reference not set to an instance of an object" error. The reason this is so strange is because I can look at the currentContext properties in the watch window. In addition, Server is not null. Because of this, I have no idea where this error is coming from. Can someone point me in the correct direction of what the cause of this could be? Thank you!

  • JPA : Inheritance - Discriminator value not taken into account in generated SQL

  • WPF Skin Skinning Security Concerns

    - by Erik Philips
    I'm really new to the WPF in the .Net Framework (get that out of the way). I'm writing an application where the interface is very customizable by simply loading .xaml (at the moment a Page element) files into a frame and then mapping the controls via names as needed. The idea is to have a community of people who are interested in making skins, skin my application however they want (much like Winamp). Now the question arises, due to my lack of Xaml knowledge, is it possible to create malicious Xaml pages that when downloaded and used could have other embedded Iframes or other elements that could have embed html or call remote webpages with malicious content? I believe this could be the case. If this is the case then I two options; either I have an automated process that can remove these types of Xaml files by checking it’s elements prior to allowing download (which I would assume would be most difficult) or have a human review them prior to download. Are there alternatives I’m unaware of that could make this whole process a lot easier?

  • JSF/Seam - new component instance on submit?

    - by purecharger
    And my confusion with JSF continues. This is a continuation of a question asked yesterday, but I feel it warrants a new question. I have a single seam component that expects a URL parameter to be injected for retrieving a List<String> from a method. This works perfectly on the first navigation to the page. The List is used to display many different selectOneRadio groups that populate a <h:form/>. Now on the submit, I cannot get the URL parameter to be injected or otherwise set on the component! Adding <h:inputHidden/> causes FacesExceptions to be thrown. Then I tried setting the List as an instance variable on the object, and when the subsequent call is made on the submit (which I also do not understand why that is done) I check to see if the variable is non-null: if it isn't, return it. Now I found that a new instance of the component is created on submit!!! getList() called this.toString(): .BeanAction@5fd98420 #### This is when submit is clicked getList() called this.toString(): .BeanAction@22aacbce The component has the following annotations: Stateful @Scope(ScopeType.CONVERSATION) @Name("bean") @Restrict("#{identity.loggedIn}") Can someone explain why there is a new instance of the component created? I'm really not quite sure how to go about handling this. I thought the hidden parameter would work, because that is how I would do it with straight HTML, and I'm a little surprised that its not working for JSF/Seam.

  • How to find NSOutlineView row index when using NSTreeController

    - by velocityb0y
    I'm using an NSTreeController to manage nodes for an NSOutlineView. When the user adds a new item, I create a new object and insert it: EntityViewEntityNode *newNode = [EntityViewEntityNode nodeWithName:@"New entity" entity:newObject]; // Insert at end of group // NSIndexPath *insertAt = [pathOfGroupNode indexPathByAddingIndex:[selected.children count]]; [entityCollectionTreeController insertObject:newNode atArrangedObjectIndexPath:insertAt]; Now I'd like to open the table column for edit so the user can name the new item. This seems logical: NSInteger row = [entityCollectionOutlineView rowForItem:newNode]; [entityCollectionOutlineView editColumn:0 row:row withEvent:nil select:YES]; However, row is always -1 indicating the object isn't found. Poking around reveals that the tree controller is not actually putting my objects directly in the tree, but is wrapping them in a node object of its own. Anyone have insight into how I would go about getting a row index relative to the outline view, so I can do this (without, hopefully, enumerating everything in the outline view and figuring out the mapping back to my node?)

  • SWFUpload Authentication

    I am using SWFUpload to do file uploading in a ASP.NET MVC 1.0 website. It is working fine, but I am not able to authenticate the upload method. The HttpContext.User.Identity.Name returns an empty string. I am assuming this is because the Flash movie is making the post. I am also using the wrapper provided here: http://blog.codeville.net/2008/11/24/jquery-ajax-uploader-plugin-with-progress-bar/.

  • Java: versioned data structures?

    - by Jason S
    I have a data structure that is pretty simple (basically a structure containing some arrays and single values), but I need to record the history of the data structure so that I can efficiently get the contents of the data structure at any point in time. Is there a relatively straightforward way to do this? The best way I can think of would be to encapsulate the whole data structure with something that handles all the mutating operations by storing data in functional data structures, and then for each mutation operation caching a copy of the data structure in a Map indexed by time-ordering (e.g. a TreeMap with real time as keys, or a HashMap with a counter of mutation operations combined with one or more indexes stored in TreeMaps mapping real time / tick count / etc. to mutation operations) any suggestions?

  • HttpURLConnection: What's the deal with having to read the whole response?

    - by stormin986
    My current problem is very similar to this one. I have a downloadFile(URL) function that creates a new HttpURLConnection, opens it, reads it, returns the results. When I call this function on the same URL multiple times, the second time around it almost always returns a response code of -1 (But throws no exception!!!). The top answer in that question is very helpful, but there are a few things I'm trying to understand. So, if setting http.keepAlive to false solves the problem, it indicates what exactly? That the server is responding in a way that violates the http protocol? Or more likely, my code is violating the protocol in some way? What will the trace tell me? What should I look for? And what's the deal with this: You need to read everything from error stream. Otherwise, it's going to confuse next connection and that's the cause of -1. Does this mean if the response is some type of error (which would be what response code(s)?), the stream HAS to be fully read? Also, every time I am attempting an http request I am basically creating a new connection, and then disconnect()ing it at the end. However, in my case I'm not getting a 401 or whatever. It's always a 200. But my second connection almost always fails. Does this mean there's some other data I should be reading that I'm not (in a similar manner that the error stream must be fully read)? Please help shed some light on this? I feel like there's some fundamental http protocol understanding I'm missing.

I ran the command 'rails server' and was returned the message below:: Usage: rails new APP_PATH [options] Options: [--skip-gemfile] # Don't create a Gemfile -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository Runtime options: -f, [--force] # Overwrite files that already exist -s, [--skip] # Skip files that already exist -p, [--pretend] # Run but do not make any changes -q, [--quiet] # Supress status output Rails options: -h, [--help] # Show this help message and quit -v, [--version] # Show Rails version number and quit Description: The 'rails new' command creates a new Rails application with a default directory structure and configuration at the path you specify. Example: rails new ~/Code/Ruby/weblog This generates a skeletal Rails installation in ~/Code/Ruby/weblog. See the README in the newly created application to get going.

  • Debugging a HTTP Handler from Visual Studio

    - by O.O.
    I am trying to debug a HTTP Handler in Visual Studio and the break point is not getting hit. Does anyone have an idea on how to go about debugging HTTP Handlers in Visual Studio? I am using VS 2010 Premium, .NET 4.0 on a Windows 7 machine. In my Web Application I have a HTTP Handler in /HTTPHandler/TrackingHandler.cs The following is in my web config file: <system.webServer> <handlers> <add name="TrackingHandler" path="/tx/*" verb="*" type="ProjectNamespace.TrackingHandler" resourceType="Unspecified" preCondition="integratedMode" /> </handlers> </system.webServer> My HTTP Handler looks like below namespace ProjectNamespace { public class TrackingHandler : IHttpHandler { public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { //Breakpoint on the very first line below string tracker = Path.GetFileName(context.Request.PhysicalPath); ....... } } } I start my Web Application using any random page in Visual Studio Debug using the builtin Web Server. I then maually edit the URL to point to the /tx/ directory and some random string after it. For e.g. my current URL looks like http://localhost:53699/tx/sdfs. I thought this should pull up the breakpoint on the first line of ProcessRequest() but it does not. I’d be grateful for any ideas. O. O.

  • APS.NET MVC Ajax: Passing a IList from the View to the Controller

    - by Bpimenta
    I need to pass the grid rows from the view to the controller using POST. The idea is to pass an IList of objects (people) that have the following structure: String Name String Address String ID I want to read the data from the JQGrid and pass it to the controller to fill the IList. I'm trying to build the data object to pass through the Ajax data parameter. Here is the Javascript code: $("#saveButton").click( function() { var returnData = '{'; var existingIDs = $('#listPeople').getDataIDs(); if (idsPeople.length > 0) { for (i=0;i<idsPeople.length;i++) { //Trying to build the obejct data ret = ret + '"people['+ i +'].Name":' $('#listPeople').getRowData(idsPeople[i]).Name + ','; ret = ret + '"people['+ i +'].Address":' $('#listPeople').getRowData(idsPeople[i]).Address+ ','; ret = ret + '"people['+ i +'].Id":' $('#listPeople').getRowData(idsPeople[i]).Id+ ','; //If it has more than one element if (idsPeople.length>1 && (i+1)<idsPeople.length) { ret = ret + ','; } } } ret = ret + '}'; My Ajax function for sending: var url_all = '<%=Url.Action("SaveData") %>; $.ajax({ type: "POST", url: url_all, data: ret, dataType: "json", success: function(){ alert("OK"); }, error: function(){ alert("Error: check SaveData"); } }); My controller: public ActionResult SaveData(IList<PeopleHeader> people){ // using debug to know if "people" variable has any values return Json(true); } The problem I'm getting is an error: "System.NotSupportedException: Fixed size collection", and no data is being delivered. I think my problem relies on creating the object... is there any simpler way of doing this procedure? Thanks in advance,

  • Mandatory profile on Terminal server fails to load. Userenv.log debug

    - by Datapimp23
    Hi, We're having a lot of corrupted profiles lately on our profile share. At the moment I have no clue why, but I decided to switch to one mandatory profile since the users can all use the same and there is no need to have seperate profiles for each user. Here's what I did. I logged into the Terminal server with a new user and configured some stuff (imported certificates and a few files). Then I logged out. Later as admin I copied the profile to another server and renamed it to bsilo. I made sure the user hive settings were adjusted. Everyone had access to the hive. I shared the bsilo folder with full access for everyone. I set the NTFS permissions to read, read & execute, list folder contents for domain users. I also renamed NTUSER.DAT to NTUSER.MAN. Now I set a env variable %manprofile% on the Terminal server that points to \server\bsilo\ntuser.man I set the env var as terminal services profile path for a test user. When I log in I as the user get the following output The system cannot find the path specified. Can somebody point me in the right direction.

  • Ajax -- re-load div on success.

    - by RPM
    I am trying to accomplish a "re-load." More specifically, I need to be able to refresh a portion of my page as a result of another successful ajax call. Moreover, I load my portion of the page via ajax which obtains it's content from an ajax post. The result is my content being displayed inside my portion precisely. I need this portion of the page refreshed after a successful ajax post. Here is some of the code: /* Ajax-- this part is loaded automatically, and I need it reloaded upon success of another ajax post. This data comes from the outcome of my other ajax function. */ $('#newCo').load('click', function() { $.ajax({ url: 'index.php?dkd432k=uBus/310/Indeed', dataType: 'json', success: function(json) { if (json['newCompare']) { $('#newCo .newResults').html(json['newCompare']); } } }); }); The next portion of code is responsible for posting the data of which I obtain in this above ajax function. function ZgHiapud (ofWhich) { $.ajax({ url: 'index.php?dkd432k=uBus/310/update', type: 'post', data: 'product_id=' + product_id, dataType: 'json', success: function(json) { $('.success, .warning, .attention, .information').remove(); if (json['success']) { $('.attention').fadeIn('slow'); $('#compare_total').html(json['total']); $('html, body').animate({ scrollTop: 0 }, 'slow'); } } }); } In the end, I need to obtain the data that I send to the server immediately upon success of the second ajax call. This data that is sent via the second ajax call needs to fire the first ajax call upon success.

  • Monitor web sites visited using Internet Explorer, Opera, Chrome, Firefox and Safari in Python

    - by Zachary Brown
    I am working on a project for work and have seemed to run into a small problem. The project is a similar program to Web Nanny, but branded to my client's company. It will have features such as website blocking by URL, keyword and web activity logs. I would also need it to be able to "pause" downloads until an acceptable username and password is entered. I found a script to monitor the URL visited in Internet Explorer (shown below), but it seems to slow the browser down considerably. I have not found any support or ideas onhow to implement this in other browsers. So, my questions are: 1). How to I monitor other browser activity / visited URLs? 2). How do I prevent downloading unless an acceptable username and password is entered? from win32com.client import Dispatch,WithEvents import time,threading,pythoncom,sys stopEvent=threading.Event() class EventSink(object): def OnNavigateComplete2(self,*args): print "complete",args stopEvent.set() def waitUntilReady(ie): if ie.ReadyState!=4: while 1: print "waiting" pythoncom.PumpWaitingMessages() stopEvent.wait(.2) if stopEvent.isSet() or ie.ReadyState==4: stopEvent.clear() break; time.clock() ie=Dispatch('InternetExplorer.Application',EventSink) ev=WithEvents(ie,EventSink) ie.Visible=1 ie.Navigate("http://www.google.com") waitUntilReady(ie) print "location",ie.LocationName ie.Navigate("http://www.aol.com") waitUntilReady(ie) print "location",ie.LocationName print ie.LocationName,time.clock() print ie.ReadyState
